1. Description of product

1.1 Description of proper use

The 1225/5 is a sewing unit which can properly be used for sewing

light to medium-weight material. Such material is, as a rule, made of

textile fibres. These materials are used in the garment industry.

In general only dry material should be sewn on this machine. The

material must not contain any hard objects.

The seam is generally made with core thread, polyester fibre

or cotton threads.

The dimensions for needle and hook threads can be taken from the

table in chapter 4.2.

Before using any other threads it is necessary to estimate the

consequential dangers and to take the respective safety measures, if

required.

This sewing unit must only be installed and operated in dry and

well-kept rooms. If the sewing unit is used in other rooms, which are

not dry and well-kept, further measures to be agreed upon may

become necessary (see EN 60204-31 : 1999).

We, as a manufacturer of industrial sewing machines, assume that at

least semi-skilled operating personnel will be working on our products

so that all usual operations and, where applicable, their risks are

presumed to be known.

1.2 Brief description

The Beisler 1225/5 is a single-head sewing unit for serging of trousers

parts with and without knee lining. The overlocking of the seat and fly

bow as well as of the trousers hem can be integrated.

For a displacement-free processing the lining is fused with the upper

fabric at a hot fusing station.

All sewing unit components are mounted on a stand welded of square

steel tubes and controlled by a microprocessor system.

The sewing unit is operated via a control panel. Here it is possible to

call up various control programs, to define new programs and to check

all inlets and outlets for maintenance and repair purposes.

4. Operation of the sewing machine head

4.1 General notes

The operation of the sewing machine head (needle insertion, threading

of needle thread and hook thread etc.) is described in the attached

separate Pegasus operating instructions.

The instruction manual is included in the accessories of the sewing

unit.

Attention: Risk of injury!

Please read the operating instructions of the sewing machine head

carefully and observe all notes on safety.

4.2 Recommended threads

Needle system: B27

Recommended

needle size: Nm 80 for very thin material

Nm 90 for thin material

Nm 100 for medium-weight material

High sewing security and good sewability are achieved with the

following core threads:

–

Two-ply polyester endless polyester core-spun

(e.g. Epic Poly-Poly, Rasant x, Saba C, ...)

–

Two-ply polyester endless cotton core-spun

(e.g. Frikka, Koban, Rasant, ...)

If these threads are not available, the polyester fibre or cotton threads

listed in the table can also be sewn.

Often two-ply core threads are offered by the thread manufacturers

with the same designation as three-ply polyester fibre threads

(3cyl.-spun).This causes uncertainty with regard to twisting and thread

thickness.

When in doubt, unravel the thread and check whether it is twisted 2- or

3-ply.

The label no. 120 on the thread reel of a core thread corresponds e.g.

to the thread size Nm 80/2 (see table values in brackets).

In case of monofilament threads you can use needle threads and hook

threads of the same thickness. The best results are achieved with soft

and elastic threads (software) of the thread thickness 130 Denier.

4.4 Setting the differential feed

By the differentials the behaviour of the feed-dogs can be altered.

Permanent differential

The left lever 2 (seen from behind) influences the permanent

differential, which is active during the whole sewing process.

The setting range is between -10 and + 6.

The higher the setting (positive numbers),the more the material is

gathered. The lower the setting (negative numbers), the more the

material is stretched.

Additional differential

The right lever 1 influences the additional differential, which is

programmable in the control and provides additional width in certain

seam sections only.

The setting range is between 0 and + 16.

The higher the positive number, the more additional lining is gathered

at the programmed positions.
